At the beginning of the period 1870–1913 the United Kingdom was the acknowledged leader in the iron and steel industry; at its end she was in some sense or other a third-rate iron and steel producer, surpassed by the United States and Germany. The first section of this paper will formulate definitions of “loss of leadership” which are statistically verifiable and economically significant, and will determine whether or not, for a given sense of the term, it is true that the United Kingdom fell behind the other countries. The second section considers some of the factors which led to the U. K.'s “loss of leadership”.

Change Mitigation

Purpose: To analyse the potential of various scenarios for reduction of carbon footprint of iron and steel sector and to reveal plausible pathways for modernisation. Design/methodology/approach: Several scenarios have been developed in order to assess the dynamics and extent of decarbonisation required to meet the global climate change mitigation target. This includes deployment of the best available technologies, increased share of secondary steel production route and deployment of innovative ironmaking technologies with various decarbonisation extent achieved in a variable timeframe. Findings: The window of opportunities to ensure compliance of steel sector development with climate goal still exists though shrinks. Modernisation shall include global deployment of best available technologies, increased share of secondary steel production and rapid deployment of innovative technologies including carbon capture and storage. Delayed modernisation will require much deeper decarbonisation, which will increase the total cost of mitigation. International policies shall be put in place to ensure availability of funding and to assist technology transfer. Short term transition strategies shall be employed as soon as possible for bridging long term climate change mitigation strategies and current state of the iron and steel industry worldwide. Research limitations/implications: Methodology applied takes into account the best available technologies and some novel ironmaking methods with the potential for commercialisation during the next decade; however, it is implied that the radically innovative iron- and steelmaking technologies with near-zero CO2 emissions will not be mature enough to deliver tangible impact on the sector’s carbon footprint before 2050. Practical implications: Obtained results can be helpful for definition of the modernisation strategies (both state-level and corporate) for the iron and steel industry. Originality/value: Dynamics and extent of decarbonisation required to meet global climate change mitigation targets have been revealed and the results can be valuable for assessment of the consistency of sectoral climate strategies with global targets.

Based on the budget of Ministry of Steel declares that steel industry contributes 2% of the Indias GDP, and its weight is 6.2% in the Index of Industrial Production(IPP). The sector able to grow by itself globally. In India steel production in one Million Tones in 1947, now its become the world's 2nd largest producer next to China. India's GDP declines 5% in 2019 on account of rising Inflation, GST and strict monetary control. This medium made the domestic demand weeker which grew 3.3% in 2019, Despite the rise in last Quater

Iron production in the iron and steel industry is a process that starts with the melting of scrap in electric arc furnaces or iron ore in basic oxygen furnaces. The proportions of the alloys in the liquid steel obtained from the liquid steel obtained by melting scrap are of great importance in order to produce the desired quality iron. In steel production, it is necessary to reduce the carbon rate to the desired level, to reduce the proportions of manganese, silicon and other chemicals to the values prescribed in the prescription, and to remove sulfur from liquid steel as much as possible. Therefore, alloys are added (FeSiMnPOTP, AltelPOTP, GrnKrbnPOTP, FeMnOrtCPOTP, KirecPOTP, FeSiPOTP, AlPOTP, FlşptPOTP etc.). Each alloy added has a chemical that acts. For example; If it is desired to change the aluminum ratio of liquid steel, AltelPOTP alloy is added. In the analysis results, it is observed that the aluminum ratios have changed. The liquid steel transferred to the ladle furnace is analyzed at certain intervals and the addition of chemical alloys continues until the required ratios are obtained. Chemical alloys added to liquid steel should not be less or more than they should be, in terms of both material and quality standards. Because the mentioned alloys are serious cost items when purchased in dollars and spread over a long term. For this reason, the rates should be adjusted very accurately. All these metallurgical processes are complex, multivariate systems. Looking at the examinations made, it is seen that while the alloys to be added to the liquid steel in the ladle furnace are rehearsed for an average of 4 times in a casting, this process is repeated at least 2 and at most 6 times. Taking samples from the liquid steel in the ladle furnace, sending the sample for chemical analysis, obtaining the result of chemical analysis and repeating these processes if the desired quality standards are not obtained, the average time is 45 minutes. These periods cause serious waste of time. For this reason, the time of the next casting has to be started later than the planned time. This causes delay in the subsequent processes (pouring liquid steel into molds in continuous casting, forming in the rolling mill, passing through quality tests, etc.). Today, with the advancement of technology, the use of artificial intelligence in the iron and steel industry will be a mandatory approach to minimize the number of proofs and minimize the loss of material and temporal labor.

Based on life cycle assessment, analysis of energy consumption and other environment load by steel production in Chinese typical iron and steel industry was carried out. The process accounted for the most environment load was found by studying the different processes in steel production route. The results indicate that the most important process is blast furnace (BF) which is the major factor of CO2 and CO emissions, and contributes most to globe warming potential (GWP) and photochemical ozone creation potential (POCP).
